FIREPLACE-HEATER.

Application filed March 14,

To all whom it may concern:

Be it known that LANDERs G. ANDERSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and Statepf California, have invented new and useful Improvements in Fireplace- Heaters, of which the following is a specification.

My object is to make a fire place heater having a radiator through which the prodnets of combustion circulate and around which fresh air circulates, so as to heat the fresh air and discharge it into the room, and my invention consists in the novel features herein shown, described and claimed.

Figure 1 is a front elevation of a fire place provided with a heater embodying the principles of my invention and taken looking in the direction indicated by the arrows 1 in Figs. 2 and 3.

Fig. 2 is a side elevation of that part of the fire place which projects into the room, as seen looking in the direction indicated by the arrows 2 in Figs. 1 and 3.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.

Fig. 4 is a staggered sectional front elevation substantially on the line 44 of Fig.3.

Fig. 5 is av vertical cross-section on the line 5-5 of Fig. 4.

Fig. 6 is a fragmentary vertical cross-section on the line 6-6 of Fig. 4.

The mantel 1 is built in front of the wall and has a chimney 2 and a fire place 3. A grate 4 is mounted in the fire place 3 some distance above the floor 5, and an ash chamber 6 is constructed below the grate, there being a door 7 in the back wall of the ash chamber so that when the door is opened the ashes and cinders may be discharged down the chute 8 into the lower part of the chimney. A draft regulator 9 is construct ed in the front wall of the ash chamber and a slatted screen 10 extends upwardly from the forward side of the grate 4. Solid walls 11 and 12 are built of firebrick or the like. from the floor up, at the ends of the ash chamber 6 and grate 4. A back fire wall 13 extendsupwardly between the walls 11 and 12 and from the back side of the grate 4 to a considerable height, and a return wall 14 extends from the upper edge of the wall 13 downwardly and backwardly, there being an air space 15 between the walls 13 and Specification of Letters Patent.

14 for circulation of air to keep the walls from burning, said walls being preferably constructed of heavy sheet iron. An air chamber 16 is formed below the ash chamber 6 and air chambers 17 and 18 are formed between the walls 11 and 12 and the side walls 19 and 20 of the mantel, there being a grille 21 covering the entrance to the air chamber 16 and grilles 22 and 23 covering the entrances to the air chambers 17 and 18, so that fresh air may pass inwardly through said grilles 21, 22 and 23. A baffle wall 24 extends downwardly from the top 25 of the fire place 3 back of the return wall 14, there being a passage 26 between the return wall 14 and the baflie wall 24, said passage leading downwardly and discharging into the lower end of the radiator 27. A flue 28 leads from the top of the fire place 3 to the chimney opening 29, there being a damper 30 at the lower end of said flue controlled by a rod 31 connected to the damper and extending through the front wall 32 of the mantel, there being a handle 33 upon the forward end of the rod in front of the mantel for operating the damper, so that when the damper 30 is opened the products of combustion from fuel burning upon the grate 4 will pass straight up through the fire place and through the flue 28 and so that when the damper 30 is closed the products of combustion must pass downwardly through the assage 26 to the radiator 27.

The details of the radiator construction 27 are as follows: The radiator is built of sheet ironand comprises means forming a heat passage 34 into which the passage 26 discharges, heat passages 35 and 36 leading upwardly from the ends of the passage 34, a heat passage 37 leading horizontally from the passage 35, a heat passage 38 extending upwardly from the other end of the passage 37, a heat passage 39 extending horizontallv from the heat passage 38, a heat passage 40 extending horizontally from the upper end of the passage 36, a heat passage 41 extending upwardly from the other end of the passage 39, a heat passage 42 extending up wardly from the other end of the passage 40,- a heat passage 43 extending horizontally from the passage 42, a heat passage 44 extending horizontally from the passage 41, a heat passage 45 extending upwardly from the other end of the passage 43, a heat passage 46 extending upwardly from the other e eer,

end of the passage 44, a heat passage 47 extending horizontally from the passage 4-6, and outlets l8 and 49 leading from'the passages 47 and l5 to the chimney openin 2-9. The sheet iron boxes forming the heat passages are mounted between upright metal bars 50 and 51, said bars being connected by bolts 52, 53, 54 and 55, certain ones of the boxes resting upon the bolts and the bolts serving to clamp the bars against the front and back sides of the boxes. In setting up the boxes forming the heat passages they are spaced apart to form fresh air passages 56, 57, 58, 59, and 61 extending forwar lly and backwardly between the boxes, and the radiator thus constructed is set in the chimney back of the fire place and. back of the batfie plate 2% so as to form fresh air passages 62 and 63 at the back and front of the radiator and communicating with the passages 56-61 through the radiator, there being a fresh air chamber 6% below the radiator to which the chambers 16, 1'7 and 18 lead. Passages lead from the top of the radiator upwardly and forwardly through the mantel and discharge through the grille 66 in the front face and upper part ot the mantel 1. In plan, the boxes forming the radiator 27 comprise straight central portions 67 and forwardly inclined end portions 68 and 69.

Correspondingly inclined clean-out openings 70 and 71 are formed through the side walls 19 and 20 of the mantel.

Openings 72 and 73 are formed in the ends of the boxes of the radiator. Covers 74 and 75 are adapted to close the openings 72 and 73 and panels 76 and 77 are adapted to close the openings 70 and 71, so that when it is desired to clean out the heat passages in the radiator the panels 76 and 7'? may be removed and the covers 7st and 75 removed and instruments inserted to clean the heat passages.

ln the practical operation, a fire is built upon the grate 4, the damper 30 is opened until the fire is well started, then the damper 30 is closed and the products of combustion will pass downwardly through the passage 26 to the passage 3% and pass upwardly from both ends of the passage 34: and then zig-Zag upwardly through succeeding passages to the outlets 48 and l9 and to the chimney opening 29. Fresh air will be drawn into the chamber G-l through the grilles 21, and 23 and pass upwardly into the air space 15 where it will be highly heated between the back 13 and the return back lei, and this fresh air will pass upwardly from the chamber 64 around the radiator and the hot air will pass outwardly through the grille 66 into the room. In this manner a large amount of the heat from the products of combustion will be extracted by the radiator and communicated to the fresh air and discharged into the room.

Various changes may be made in the details of construction without departing from the spirit of my invention as claimed.

I claim:

1. ll lire place heater comprising a grate, a back wall. extending upwardly from the grate, a return wall extending downwardly from the upper edge or the back wall; there being a fresh air space between the two walls, an ash chamber ielow the grate, means forming a fresh air passage below the ash chamber and behind the walls, a radiator mounted in the fresh air passage and consisting of horizontal boxes spaced apart and forming back and forth passages for the products of combustion and having cleanout openings in their ends, said clean-out nings being accessible through openings in the sides of the mantel, and means for conducting the products of combustion from above the grate through the radiator.
